[Bug c++/45334] New: Base class type information not accessible in binaries compiled with g++ 4.5.0

[andre dot poenitz at nokia dot com]

This is a copy of an issue originally filed as gdb bug at
http://sourceware.org/bugzilla/show_bug.cgi?id=11639 that was identified as a
gcc issue in the mean time:

If 'Derived' and 'Base' are setup as shown in the attachment

void Derived::foo()
{
    Base *b = this;
    Base &br = *b;
}

then

 'print b'

yields  "$1 = (void *) 0xbfffee38", i.e. the type information for 'b' is
completely lost.

It should print (Base *) 0xbfffee38. 

The problem is not present in g++ 4.4.
